Original No. 1,270,327, dated June 25, 1918, Serial No. 101,959, filed June 6, 1916. Application for. reissue led January 31, 1920.

To all linkom it may concem:

Be it known that I, EDWARD EDWARD' i along the lines 2-2 of Fig. 1.

Fig. 3 is a plan view of the valve showing the rack and pinion mechanism.

Fig. 4 is a vertical section on the line 4 4 of Fig. 2 or Fig. 3.

Fig. 5 is a front elevation of the rack support, and

Fig. 6 is a perspective of the revoluble shutter.

Similar numerals refer to similar parts throughout the several views.

My valve consists generall of a conductor in which are interpose shutters or vanes which may be allowed to remain open and permit the flow of substance through the valve, or may be closed to cut off such flow. T'he conductor consists of two similar casing parts 10 and 11 square exteriorly and each provided with a boss 12 or 13 on the end adjacent the other part. Interiorly the conductor is generally circular and preferably threaded to facilitate the insertion into a pipe line. At the end nearer the other part, however, the conductor parts are recessed, as at 14, to form the square pocket 39, which forms'the valve chamber proper. The boss on the exterior of the casin parts is provided for the purpose of securlng toget ier the two parts and for that purpose is provided with holes 24, as shown, and in each hole is inserted a bolt 26 held in place by the nut 25. On the line of junction of the two parts and properly spaced are selected the centers of rotation of the shutters or vanes within the valve chamber. As illustrated, there are four of these shutters and accordingly four holes 22 are provided on the line of junction on the upper side of the casing and extending through, as shown, into the valve chamber 39. The holes are continued in the lower section of the cas-:ingl

at 23, but are not carried through to the outside. In these holes are mounted the axes of the revoluble shutters. Obviously, any desired number of shutters may be employed.

Each shutter is composed of a central and principal portion 16, flat and thin, and extending from this downward is the axis 19 which ente-rs the hole 23, and extending upward from the body is the axis 20, which enters the hole 22 and is of proper length to extend in the hole 22 to slightly above the top of the casing boss 12-13 and there carries the se ental inion 21. These axes are inserte into eit er part of the casing, and the two parts of the casing then clamped together eiiectually securing the axes in place.

Provided on the casing part l1 inside the valve lchamber 39 are two projections 18 for a purpose now to be described. These projections extend the full length'of the valve chamber 39 and project inwardly toward each other in angular form. When the vanes 16a and 16c are rotated clockwise, as shown in Fig. 2, and the vanes 16b and 16d are rotated counter-clockwise, the outer edges of 16 and 16d will Contact with the angular surfaces of the projections 18, the inner edges ot these vanes contacting with the outer edges respectively of the vanes 16b and 16", and the inner edges of the latter two vanes will contact each with the other. The opening Will thus be closed.

To thus operate the vancs I utilize the segmental pinions mounted on the upper ends of the axes 20. I provide on the sides of the bosses 12 and 13 two uprights 33, each secured to the boes by screws 35, and each provided near the upper end and immediately above the top of the bosses, with a slot 34. In these slots slides a flat rack member 27. This rack member is widened at the center portion at the shoulders 32, and this center portion then consists of two end kpieces connected by two side pieces 28,

which latter are provided on their inner edges with teeth 29 and 29. These teeth mesh with the teeth of the segmental pinions 21, each rack meshin with alternate pinions, and thus motion o the rack in one direction produces rotation of each alternate pinion in one direction, and of the remaining pinions in the opposite direction. The

' is moved' toward the left in Fig. 1. During.

movement of the rack member isv limited by `spring 36 is connected to the rack member by a stud and the other end of the spring is secured to one of the screws 35.

It will be clear 'from `the above that the valve operates as follows: Starting with the position shown in the illustrations, the rack this motion, the rack 29 rengages with the pinions 21l and 21'c and rotates them and the vanes 16*l and 16c in a clockwise direction. At the same time the rack 29' engages the pinions 21" and 21 and rotates themA and the' vanes 16b and 16d inl a counter-clockwise direction, thus closing the valve as eX- plained above. Reverse motion of the rack then opens the valve.

It will be apparent from the above that I have provided a valve readily inserted into' any pipe line, that the valve acts with very slight motion of the controlling member, and that the action, therefore, may be made very rapid.

ltis apparent that modifications may be made in the valve, principally perhaps in the number of vanes, the outlines of the casing parts, and the mea-ns provided for securing the valve in the conduit. All these, in so far as they are within the scope of the appended claims, consider as within the scope and part of myv invention.
